Fault: Stage is oscillating or positions inaccurately
Possible Causes Solution
Electromagnetic signal
causes noise of the
sensor signal.
Check the sensor signal.
If the sensor signal seems to be abnormal:
Avoid interfering signals.
Take particular care to ensure suitable shielding and grounding. For more
information, download the “Guide to Grounding ans Shielding” from our
website:
1) Open the website www.pi.ws.
2) Search for A000T0074.
3) In the search results, click the Downloads tab.
4) Download the Technical Note A000T0074 “Guide to Grounding and
Shielding”.
Reading/writing
parameters from/to
nonvolatile memory
While parameter values are being read from or written to the nonvolatile memory
of the E-727, the servo mode is temporarily switched off. This may lead to faulty
control or large position errors.
Observe the following when you use the commands SEP, SEP?, RPA, WPA, or
the corresponding operating elements in the PC software:
- Avoid motions of the axes.
- Do not carry out measurements with the axes.
Fault: The customer software does not run with the PI drivers
Incorrect combination
of driver routines/Vis
Check whether the system works with a terminal program.
If so:
Read the information in the corresponding software manual and compare the
sample code on the product CD with your program code.
Fault: The Device Parameter Configuration window is not available in PIMikroMove.
Possible Causes Solution
NI LabVIEW Run-Time
Engine has not been
installed
Install the NI LabVIEW Run-Time Engine, see "Performing the Initial Installation"
(p. 43).
If the problem that occurred with your system is not listed in the table above or cannot be solved
as described, contact our customer service department (p. 234).
